Warm two tone flavored dentifrice

Abstract

There is disclosed an anhydrous heat releasing, two toned flavored dentifrice which contains the abrasive system consisting essentially of an anhydrous synthetic zeolite and an anhydrous dentally acceptable, substantially water-insoluble polishing agent, and a flavoring agent as the essential ingredients.

We claim: 
     
       1. An anhydrous heat releasing dentifrice which generates heat in the mouth and effects a two tone flavor change in the oral cavity comprising an abrasive system consisting essentially of a finely divided anhydrous synthetic zeolite having an appreciable heat of hydration and capable of being reversibly dehydrated in amounts of about 10-50% by weight, and about 5-20% of a finely divided anhydrous dental abrasive to decrease the abrasivity and regulate the degree of heat generated by said dentifrice, about 0.1 to 5% by weight of at least one flavoring agent, and about 20 to 75% of an anhydrous liquid vehicle. 
     
     
       2. A dentifrice according to claim 1, wherein the snythetic zeolite is a crystalline metal alumino-silicate, said metal being selected from the group consisting of an alkali metal, alkaline earth metal, zinc, copper and mixtures thereof. 
     
     
       3. A dentifrice according to claim 2, wherein the liquid vehicle is an anhydrous humectant or oil selected from the group consisting of glycerine, propylene glycol, polyethylene glycol, mannitol, polypropylene glycol, sorbitol, liquid light petrolatum, mineral oil, vegetable oil, and suitable mixtures thereof. 
     
     
       4. A dentifrice in accordance with claim 1, which additionally contains about 0.5 to 5% of a surface-active agent. 
     
     
       5. A dentifrice in accordance with claim 3, which also includes a gelling agent selected from the group consisting of sodium carboxymethyl cellulose, hydroxyethyl cellulose, polyvinyl alcohol, Irish moss, silica aerogel, and mixtures thereof. 
     
     
       6. A dentifrice according to claim 5, which also includes about 0.5 to 5% of a synthetic anionic surface-active agent. 
     
     
       7. A dentifrice in accordance with claim 6, which also contains a sweetening agent and wherein the flavoring agent is a flavoring oil in an amount of about 0.5 to 2% by weight. 
     
     
       8. A dentifrice in accordance with claim 1, wherein the additional dental abrasive is amorphous alumino-silicate. 
     
     
       9. A dentifrice in accordance with claim 1, wherein the dental abrasive is finely divided silica.
